Introduction:Fossil fuels such as oil and coal
are nonrenewable, that is, they draw on finite resources that
will eventually dwindle, becoming too expensive or too environmentally
damaging to retrieve. In contrast, renewable energy resources –
such as wind and solar energy – are constantly replenished and will
never run out. Most renewable energy comes either directly or
indirectly from the sun. Wind Turbines have a long history and they
date back to the ancient times. They have been used through
history and they are still in the process of development. Windmills may
be used to do a work such as grinding grain into flour or pumping water
out of a water well. They may also be used to create electricity.

In this project we will study the parts of
a windmill and make a model of a windmill.

Material and instructions:Making a model of a windmill
is a good way to learn about the windmill parts. You may also use your
model to do some additional experiments and see how much wind power can
be converted to work in your windmill. When you select this project, you
can also study questions such as:

Which blade variables have the
greatest affect on windmill efficiency?

What is the effect of wind speed on
energy production of a windmill?
